What is the primary cooking technique used for preparing Belgian waffles?

The primary cooking technique used for preparing Belgian waffles is indeed baking. This method involves cooking the batter in a waffle iron, which is designed specifically to cook the batter evenly while creating the iconic crispy exterior and soft interior of the waffle. The heat sources within the waffle iron surround the batter, allowing it to rise and achieve its characteristic texture and shape.

Baking is essential in this context as it allows for controlled, dry heat to cook the batter, helping achieve the right consistency and flavor. Unlike other cooking methods, such as frying, which might cause the waffles to become greasy or too heavy, baking ensures a light and fluffy outcome. Grilling and steaming wouldn't provide the same results since grilling is typically used for flat foods and steaming does not create the desired crispy texture associated with Belgian waffles.
